Answer:

31.5%

Step-by-step explanation:

If 70% of customers get an oil change, and 45% of those get their tires rotated, then this is a method I use to find the answers to these types of problems.

70% of customers, 45% of 70

One method that will help you so much is this simple equation: x% of y= y% of x. For example, if you need to find 3% of 50, the same value is given for 50% of 3, which would be 1.5. Using our given digits,45% of 70 is the same as 70% of 45.

A method that can add on to this is one I've come up with myself. If you divide your original number by 100, then multiply it by your given percentage, it will give you your wanted value, so if you plug in your values, 70/100, multiplied by 45, will equal 31.5%.

musickatia [10]

Answer:

10.94% to the nearest hundredth.

Step-by-step explanation:

That would be (14200 - 12,800) * 100 / 12800

= 10.94%

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).

Lapatulllka [165]

Hello!

The formula for the area of a sector can be written as follows:

Area = $\frac{1}{2}$ $r^{2}$ (R)

In the above formula, “r” represents the radius while “R” represents the radian measure of a sector. The radius is given to us in the image above as 10 inches. However, we still need the radian measure of the two sectors. To find this measure, we can use the following conversion:

1 degree = $\frac{pi}{180}$ radians

Because the two sectors have a given measure of 72 degrees, we need to multiply both sides of the above conversion by 72:

72 degrees = $\frac{72pi}{180}$

Reduce the fraction on the right side of the equation:

72 degrees = $\frac{2pi}{5}$

We now have the radian measure of both sectors. Now simply insert this and any other known values into the “area of a sector” formula above:

Area = $\frac{1}{2}$ $10^{2}$ ( $\frac{2pi}{5}$ )

Simplify the right side of the equation to get the following answer:

Area = 20 pi

We have now proven that the area of one sector is equal to 20 pi.

If, however, you need the combined area of the two identical sectors, simply multiply the proven area by 2 to get a total area of 40 pi.

I hope this helps!
